Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number

Step-by-step explanation:

The base of the exponential factor in a growth formula is the growth factor. Here, that is 1.30. It represents the multiplier of the number of spores each week.

Putting 4 into the formula, we find ...

  f(4) = 345×1.30^4 ≈ 985 . . . . mold spores after 4 weeks

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
